  • Emotional Dysregulation and ADHD

    One of the many great contributions of Dr. Russell Barkley was his conceptualization of ADHD as a disorder of self-regulation. ADHD people have difficulties regulating their behavior, which lead to the classic diagnostic criteria of hyperactivity and impulsivity and they have problem regulating cognitive processes which leads to the well-known inattentive diagnostic criteria for the disorder. In a 2010 paper, Dr. Barkley argued persuasively that deficient emotional self-regulation should

  • Working Memory and ADHD

    This blog addresses the relationship between executive function deficits in general and working memory (WM) deficits in particular and attention-deficit/hyperactivity disorder (ADHD). Although some neuropsychological models of ADHD have proposed that ADHD arises from deficits in executive functions, accumulating clinical evidence show that it afflict some but not all individuals with ADHD and suggests that ADHD and executive function deficits represent separate clinical condition. Because

  • Stimulant Medication and Psychotic Symptoms in Offspring of Parents With Mental Illness

    Pediatrics 2016; 137(1);e20152486 “Stimulant Medication and Psychotic Symptoms in Offspring of Parents With Mental Illness” MacKenzie, L.E., Abidi, S., Fisher, H.L. et al.

  • Are Executive Function Deficits Separate from ADHD?

    This blog addresses the relationship between executive function deficits in general and working memory (WM) deficits in particular and attention-deficit/hyperactivity disorder (ADHD).  Although some neuropsychological models of ADHD have proposed that ADHD arises from deficits in executive functions, accumulating clinical evidence show that it afflicts some but not all individuals with ADHD and suggests that ADHD and executive function deficits represent separate clinical

  • Side Effects of Acetaminophen – ADHD?

    The use of acetaminophen by pregnant women in one study showed increased risk for ADHD in the child. However, looking at more studies, the results are not yet conclusive.
  • Acetaminophen and ADHD

    Many media outlets have reported on a study suggesting that mothers who use acetaminophen during pregnancy may put their unborn child at risk for ADHD. Given that acetaminophen is used in many over-the-counter pain killers, correctly reporting such information is crucial. As usual, rather than relying on one study, looking at the big picture using all available studies is best. Because it is not possible to examine this issue with a randomized trial, we must rely on naturalistic

  • Broken Bones and ADHD

    Although some people view the impulsivity and inattentiveness of ADHD adults as a normal trait, these symptoms have adverse consequences, which is why doctors consider ADHD to be a disorder. The list of adverse consequences is long and now we can add another: broken bones. A recent study by Komurcu and colleagues examined 40 patients who were seen by doctors because of broken bones and 40 people who had not broken a bone. After measuring ADHD symptoms in these patients, the study found that

  • Non-Stimulant ADHD Medication (Guanfacine) as an Adjunct to ADHD Stimulant Medications

    ADHD stimulant medications can be supplemented with ADHD non-stimulant medications for more tailored effects without increasing identical side effects. This study in guanfacine is an example of a beginning of research for ADHD in Adults.
